Still trying to hide tabs

I’ve been wanting to hide tabs on my wiki page for ages now. http://www.science2point0.com/wiki – particularly the dicussion and links tab, which are plugins, they do not have an id to add to display none in css. What should I be putting?

If you find something, let’s sayadd_action( 'bp_nav_items', 'add_discussion_tab_function' );
copy that line, change ‘add_action’ to ‘remove_action’, and put it in the functions.php file of your theme. That should make sure that the tabs don’t appear.
